COMPARISON OF PROTEIN-METABOLISM AND GLUCOSE-UPTAKE IN TURKEY (MELEAGRIS-GALLOPAVO) SATELLITE CELLS AND EMBRYONIC MYOBLASTS IN-VITRO

Protein synthesis, protein degradation, and glucose uptake were compar ed in clonal-derived turkey myogenic satellite cells (clone DS-SC) and embryonic myoblasts (EM) and between satellite cell cultures from Nic holas (DN) and Merriam's (WM) turkeys. Protein synthesis rates were hi gher and degradation rates were lower in myotube cultures of D5-SC com pared with EM (P less than or equal to 0.05). Protein synthesis and de gradation rates did not differ between cultures of DN and WM (P greate r than or equal to 0.05). Glucose transport rates were significantly h igher in EM than DS-SC cultures and did not differ between DN and WM c ultures. Insulin-like growth factors and insulin stimulated protein sy nthesis, decreased protein degradation, and increased glucose uptake i n all cell lines.
